JPH06265168A - Controlling method of let-out air in air conditioner - Google Patents

Abstract

PURPOSE:To improve the feeling of conditioned air of a person in the room and also the distribution of a room temperature and to reduce the feeling of draft in a cooling operation by giving fluctuation to let-out air. CONSTITUTION:Horizontal outlet louvers 20 and 23 are provided horizontally above and below at a prescribed space between them in an air outlet 5 and they are driven by discrete motors 26 and 27 respectively. The horizontal outlet louvers 20 and 23 are rotated periodically in reciprocation to be in a state wherein a space between the fore ends on the outlet side thereof is narrowed and in a state wherein it is widened, and thereby let-out air is converged and diffused repeatedly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling blowout air in an air conditioner.

[0002]

2. Description of the Related Art A vertical sectional view of a conventional wall-mounted indoor unit of a separation type air conditioner is shown in FIG. In FIG. 2, reference numeral 1 is a main body casing, 2 is a front panel attached to the front surface of the main body casing 1, and 3 is a plate fin tube type heat exchanger arranged so as to face a suction grill 2a formed in the front panel 2. Vessel 4 is heat exchanger 3
The cross-flow type fan 5 disposed at the lower rear part of the front panel 5 is an air outlet formed at the lower part of the front panel 2, 6a, 6b.
Is a horizontal outlet louver which is disposed in the air outlet 5 and extends horizontally, 15 is a vertical louver which is disposed in the air outlet 5 and extends vertically, 7 is a drain pan disposed under the heat exchanger 3, and 8 Is an air filter arranged on the back surface of the suction grill 2a.

The horizontal blowout louvers 6a and 6b are connected to each other by a stay 9 so as to be parallel to each other with a space therebetween, and a shaft 10 fixed to the stay 9 is rotated around a shaft 10 by a motor (not shown). And rotate.

Vertical louvers 15 are pinned at intervals in the left-right direction.
A large number of these vertical louvers 15 are rotatably supported by the main body casing 1 via 11 and are projections provided on the lower surface of the rear end thereof.
By moving the slider 13 engaged with 12 in the left-right direction, the slider 13 is rotated around the pin 11 while maintaining the parallel state to each other.

During operation of the air conditioner, the fan 4 rotates,
Refrigerant from an outdoor unit (not shown) circulates in the heat exchanger 3. Then, the indoor air becomes
When the air is sucked from the suction grill 2a into the body casing 1 and passed through the air filter 8, dust contained therein is removed, and then heat is exchanged with the refrigerant in the process of passing through the heat exchanger 3 to cool or cool. After being heated and then sucked into the fan 4 and urged, the vertical louver 15 and the horizontal blowing louvers 6a and 6b regulate the blowing direction, and the air is blown from the air outlet 5 into the room.

[0006]

In the above conventional air conditioner, since the two horizontal blowing louvers 6a and 6b integrally rotate around the horizontal shaft 10, the blowing direction of the blowing air is changed. I could change it up and down, but I couldn't adjust the wind speed and I couldn't give fluctuations to the blowing air.

SUMMARY OF THE INVENTION The present invention has been invented to solve the above-mentioned problems, and its gist is to provide a plurality of horizontal blowout louvers at an air blowout port at predetermined vertical intervals. In an air conditioner in which the horizontal blowout louvers are horizontally arranged apart from each other and each of which is driven by an individual motor, the horizontal blowout louvers that are adjacent to each other are widened when the distance between the tips on the blowout side is narrowed. There is provided a method for controlling blowout air in an air conditioner, which is characterized in that the blowout air is controlled so as to converge and diffuse repeatedly by periodically reciprocally rotating depending on the state.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. The horizontal blowing louver 20 is fixed to the shaft 22 via the arm 21, and the horizontal blowing louver 23 is fixed to the shaft 25 via the arm 24. The shafts 22 and 25 are arranged at the upper and lower sides of the air outlet 5 so as to be parallel to each other with a predetermined space therebetween, and both ends thereof are rotatably supported by the front panel 2.

The shaft 22 is driven by a motor 26 linked to one end thereof, and the shaft 25 is driven by a motor 27 linked to the other end thereof. In addition, in FIG. 1, 28 is a stabilizer.

The horizontal blowout louver 20 and the horizontal blowout louver 23 are periodically reciprocally rotated in synchronization with each other such that the interval between the tips on the blowout side becomes narrow and wide. It is desirable that this cycle be the same as that of natural wind. Other configurations are similar to those of the conventional one shown in FIG. 2, and corresponding members are designated by the same reference numerals.

However, since the wind velocity can be increased by converging the blown wind, the blown wind can reach a distant place, thereby improving the room temperature distribution. Moreover, since the wind speed can be reduced by diffusing the blown air, the draft feeling during the cooling operation can be reduced. By periodically repeating the convergence and diffusion of the blown air, it is possible to give fluctuations to the blown air, thereby improving the air conditioning feeling of the person in the room.

When three or more horizontal louvers are provided, the adjacent horizontal louvers may be periodically reciprocally rotated in synchronization with each other.

[0013]

According to the present invention, the horizontal blowing louvers adjacent to each other are periodically reciprocally rotated so that the distance between the tips on the blowing side becomes narrow and the distance becomes wide. Can be repeated.
As a result, fluctuations can be given to the blowing air, the room temperature distribution can be improved, and the draft feeling during the cooling operation can be reduced to improve the air conditioning feeling of the person in the room.
